WINDMILL PUMP AND REGULATOR.

SPECIFICATION forming part of Letters Patent No. 392,852, dated November13, 1888.

Application filed May 17, 1886.

To all whom it may concern:

Be it known that I, GEORGE A. CARTER, a citizen of the United States,residing at Des Moines, in the countyof Polk and State of Iowa, haveinvented certain new and useful Improvements in \Vindmill Pumps andRegulators; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in IO the art to which it appertains to make and use the same.

My invention relates to an improvement in windmill pumps and regulators,and particularly to that class wherein, when the tank has I 5 beenpumped full, a. float and valve cut off the supply and cause the waterto'rise in a cylinder and raise a piston, which, acting on a weightedlever, furls the sails of the wind wheel, and by other similarconnections likewise unfurls the sails when the water in the tank fallsbelow a certainlevel; and it consists in the combination, with the frameof a forcepump, of the device for furling and unfurling the sails, tothe end that it may be acomplete adjustable article when it leaves thefactory,

*capable of being properly set and connected without any particularskill, all as will be more fully hereinafter described and claimed.

For a better understanding of the improvements in detail, attention isinvited to the accompanying drawings, in which Figure 1 is a frontelevation of my improved 'devices, partly in section; Fig. 2, asideelevar tion with the device for furling and unfurling the sails omitted;Fig. 3, a detail, partly in section, of the stuffing-box and its lowerbearing; Fig. 4, a detail in plan of the air-chamher and the bucket orupper bearing for the stuffing-box, and Fig. 5 a section through the 40air-chamber on the line as m of Fig. 2.

Like letters of reference denote corresponding parts in the severalviews.

A denotes a casting, which constitutes the upper guide for the pump-roda, and in which the two tubes b I) are secured, preferably byset-screws, so as to be removable, said casting having suitable holes,a, to receive bolts for securing it to the upright plank A. (Shown inFig. 2.)

B is another casting,likewise adapted for attachment to plank A, andwhich serves as a Serial No. 202,443. (No model.)

lower guide for the pump-rod a and a further support to the tubes 1) b,which pass through it and down through another casting, O, which isscrewed or bolted to the platform X of the well, to prevent the partsfrom becoming loose and having lateral motion.

In the well, a little distance below the platform X,is an air-chamber,D, bolted to a base, D, and provided on top, at diagonally-oppositepoints, with two ears, 0 c, to receive the tubes 1) b, and furtherprovided between these ears with a separable bearing or bracket, d,which constitutes the upper bearing for a stuffing-box, E, through whichpasses the pumprod a down to its head in the pump-cylinder F. Thisstuffing-box is of tubular form, and is made long enough to extend downto a T-bracket, E, having side flanges, e e, bolted to the base D. Thesaid stuffing-box is screwed into the bracket E, and, by reason of itsextraordinary length, strengthens the whole against lateral vibrationand insures absolute vertical movement of the pump-rod a. Into thebottom of this bracket is screwed the pipe F, which supports thepump-cylinder F. Atube, f, leads from the bracket E through the base Dinto the bottom of the air-chamber D, where it is covered by a hingedcheck-valve, f, whereby any water is prevented from returning to thewell after entering the air-chamber from this tube. Other tubes, 99,lead in opposite directions from the bottom of the air-chamber D,through the base D into cylinder G and valvechamber G, which aresupported by the base D upon opposite sides of the air-chamber D.

Within the chamber G is a ball or any other suitable valve, h, actuatedby a rod, h, which extends through the tube b, (screwed into saidchamber and into an arm, I, on the upper end,) and is provided on itsupper end, which is screw-threaded, with a hand-wheel, h By turning thishand-wheel, and thereby depressing this r0d,communication is openedbetween the chamber G and its tube 1), and water is delivered from thepump proper through the tubesf and g, and up through the said tubeb tothe spout J, which is secured to said tube above its bearing in thecasting B. By raising this rod the valve h is returned to its normalposition and cuts off the supply of water up through the tube 1), andallows the water to be ICO delivered into a pipe, K, connected to thebottom of the valve-chamber G, which pipe conducts the water up to atank, L, situated above the ground at any desired distance from the wellor spring in which the pump is placed. This pipe K. extends into saidtank, andv has on its upper end a hinged valve, 7', controlled by alever, 7r, having connections by wire or rope with a float, M, which.rises with the waterin the tank until the water reaches a certain level,when the short end of the lever is presses down upon the valve j andcloses the end of the pipe, so that no more water can flow into thetank. Then this action takes place, the pump forces the water into theregulating-cylinder G, which is mounted upon the distributingbase D, andraises its piston N, whose rod N passes up through the tube b on thisside, and is connected at its upper end to a weighted lever, O,which isfulcrumed upon the arm I of the pump-frame above the platform of thewell, and to this lever is attached the furling-rod m or a, as the casemay require. For instance, the rod m is for connecting the lever withthe sails of a windwheel in which the rod is to be pushed up to furl.the sails, and the rod a is for connecting the lever with the sails of amill in whichthe rod is to be pulled down to furl the sails.

The pump-rod a may be connected to the windmill in any wellkn own way.

The link 1) and its handle I are attaehcd to the pump, so that water canbe obtained when the mill is not in operation.

The operation of my improved pump and regulator is as follows: \Vhen themill is in operation,water is delivered by the pump into theair-chamber, and thence through the sev eral outlets and pipes into thetank above the ground. When the supply to the tank is cut off, thepressure increases in the pipes and the water is forced into thecylinder G, so as to cause the piston N to rise, and likewise theweighted lever 0, whereby either the furlingrod m or a is operated tofurl the sails of the wheel and thus stop the pump. When the water hasbeen drawn from the tank and the float dropped down to a certain level,water will again commence to flow into the tank, thus relieving thepressure from under the piston, which will then be forced down by theweighted lever and the sails unfurled to the wind.

It will be seen that by attaching the regulating-cylinder to thepump-frame below the platform of the well and by fulcruming the weightedlever upon the pump-frame above said platform I have made a verysubstantial improvement upon the old form of windmill pump andregulator,which, being furnished to the trade in parts or sections,required considerable skill in setting up, and even then it would failto work satisfactorily on account of imperfect setting of the parts. Asit is now, theentire device is complete when it leaves the factory,requiring only to be set in place and conneeted to the windmill anddistributing-pipes.

It will further be seen that by placing the cheek-valve inside of theair-chamber all watcr is prevented from returning to the well. when thepump is at rest, so as to prevent the unnecessary action of theregulatoror the withdrawal of water from the tank.

I do not wish to be confined to a ball-valve for regulating the supplyof water up through the tube Z), for a three-way cock in the tube justabove the base would accomplish the purpose, and in fact there are manysuch devices which are well. known and capable of use for the purpose.

It must be understood that the windmillrcgulator is not to be confinedto a pump of the construction herein described and illustrated, as it isjust as well adapted for use with any other force-pump of this class.

So much of this application as relates to the attachment of thepump-cylinder and connecting parts to the distributing-base I intend tointroduce as the subject of a future application on a foree-pu mp, andhence claims to the same are designedly omitted in this application.

I do not broadly claim as my invention the employment of the cylinderand its piston as a windmill-regulator; but
